solve equation x^2+2√3x+3=0 using formula
Answers
Answer:
The first term is, x2 its coefficient is 1 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is +3
Step-1 : Multiply the coefficient of the first term by the constant 1 • 3 = 3
Step-2 : Find two factors of 3 whose sum equals the coefficient of the middle term, which is -3 .
-3 + -1 = -4
-1 + -3 = -4
1 + 3 = 4
3 + 1 = 4
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Equation at the end of step 1 :
x2 - 3x + 3 = 0
Answer:
Step-by-step explanation:
Here in this quadratic eqn, a=1, b=2root3, c=3
Quadratic formula: (-b+square root of b^2-4ac/2a or -b-square root of b^2-4ac/2a)
Discriminant(D)= b^2-4ac
=> 12-12= 0...
Since, D=0, the gn quad.eqn has 2 equal roots,
i.e, -b/2a= -2root3/2
=> -root3..........
